First, thanx for looking into this.
I've just gone over all this and a bunch of the doc. again to refresh my memory. I had a really long response that was incorrect in places but got me to the following. I'll spare you the details.
I think in the case in this post confusion arose because ANY looked like an auxiliary of some kind on the part of speech when in fact its a wildcard. And because VERB is a valid value for the part of speech and the details, though alas with differing meaning. If I was to offer any input on your change above I would say this. Rather than "The [ANY] tag looks for any tag details connected with a word (morphological tag), but excludes the part of speech detail." I would replace the bold with "without constraining the part of speech" or some such thing. Thus, ANY stands in for all (or any) parts of speech, is a wildcard.
In fact it looks to me like the first word, and it only, is always the part of speech (the doc almost says this) and that when one does not want to constrain it one must use something to indicate that and "ANY" is that beastie.
Please don't assume I know anything. I'm just trying to help out. Please check for sanity of my comments with those who know. I would not want factually incorrect information based on my lunatic theories to gain any currency.
